Original SJ Xeno impregnation = eagle eating Prometheus' liver?

I feel like this is so obvious it has surely been discussed before, so I apologize if it has, but I was watching the Wondercon interview with Ridley and Damon yesterday and I've been thinking about the question towards the end where the guy mentions Lucifer enlightening man and asks how this story relates to religion. This morning I realized that having an xeno burst out of your chest, like the SJ in the chair Alien experienced is pretty similar to having your liver pecked out by an eagle, and with all the references the ancient alien theory, a rogue SJ visiting earth and bestowing technology, speeding up evolution, or meddling in some other "forbidden" way and being punished with impregnation seems a pretty perfect fit. I also think it would be pretty brilliant to build the xenos into the SJ's culture for thousands or millions of years via a punishment for those that disobey norms. Then again, it really does look like he was headed somehwere with a shipment of eggs and Ridley specifically mentions the questions of where he was going with that "cargo" in an interview. So, it doesn't quite explain everything. Thoughts?
